Rachel and paula want to know who reads more pages per hour. rachel keeps track of the number of pages she reads in a graph, and paula keeps track of how many pages she reads in a table. how many pages per hour does each girl read, and who reads at a faster rate? rachel: pages per hour paula: pages per hour the person who reads faster is: (type r for rachel or p for paula) first-quadrant graph showing a ray from the origin through the points 2.5, 85), (4, 136), (5.5, 187), and (6.5, 221). horizontal axis label is time in hours. vertical axis label is pages read. paula’s reading log time (h) 2 3.5 5 7 pages read 64 112 160 224

Піf x = y and y= z, which statement must be true? оа. -x = -2 b. x= z ос. —x = 2 od. 2= x

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
